Toshiba's storage division today said that it has produced the world's highest-capacity, 1.8-inch hard drive, delivering nearly 100GB of storage. The new drive uses perpendicular magnetic recording, where bits are aligned vertically on the platter, to achieve the record-setting density, according to Electronista. The small disk mechanism also spins at a relatively quick 4200RPM and consumes less power per gigabyte than earlier models, ensuring that it remains efficient enough to be used in iPods and other handheld devices without sacrificing speed. Toshiba plans to start manufacturing the 100GB model in January with devices using its extra storage soon afterwards.
